Best internal comms stack for eng announcements + RFCs?

The ideal internal communications stack for engineering teams divides tools by velocity and durability , ensuring that long-form architectural reviews do not get lost in chaotic chat apps.

An effective engineering stack separates the Source of Truth (where RFCs live), the Amplification Layer (where announcements happen), and the Discussion Layer (where feedback is gathered).

1. The GitHub / Git-Based Stack (Best for Pure Dev Culture)

This stack treats architectural documentation like code, enforcing high engineering rigor and seamless version control.

• Source of Truth (RFCs): A dedicated rfc repository on GitHub (or GitLab) using Markdown files. Proposals are submitted via Pull Requests (PRs).
• Discussion Layer: PR comments and inline review features.
• Amplification Layer (Announcements): An integrated Slack app or custom webhook (e.g., via GitHub Actions) that automatically pings a dedicated #eng-announcements or #active-rfcs channel when a PR is opened or merged.
• Why it works: Keeps developers in their primary environment. It provides explicit tracking for when an RFC moves from "Proposed" to "Approved/Merged".

2. The Notion / Confluence Stack (Best for Cross-Functional Context)

This setup functions best when engineering needs to collaborate with Product, Design, or Security teams who may not regularly use Git workflows.

• Source of Truth (RFCs): Notion or Atlassian Confluence using a standardized Lightweight RFC Template.
• Discussion Layer: Inline rich text comments directly inside the document workspace.
• Amplification Layer (Announcements): A pinned database view tracking statuses (e.g., Draft, Under Review, Approved ) paired with automated email digests or an internal engineering newsletter system like Axios HQ or Workshop.
• Why it works: Simplifies the inclusion of non-technical stakeholders, supports embedded diagrams (like Mermaid or Miro charts), and maintains a highly searchable, visual wiki layout.

3. The Documentation-First Stack (Best for Scaling & AI Readability)

A modern approach built specifically for technical document management, minimizing the layout chaos commonly found in generic wikis.

• Source of Truth (RFCs): Dedicated technical documentation hubs like Mintlify or Slab . Mintlify allows teams to keep documents in Git as MDX files while rendering them as a beautifully structured internal site.
• Discussion Layer: Slack threads or native doc comments depending on whether the review is async or immediate.
• Amplification Layer (Announcements): Internal changelog modules natively built into the documentation platform or broadcasted via Slack workflows.
• Why it works: High discoverability. These platforms natively format code blocks and structural diagrams cleanly, and structure data optimally for internal AI search tools.

3 Unbreakable Rules for Engineering Announcements

To provide a more tailored stack suggestion, tell me:

• What is the approximate size of your engineering organization?
• Do product managers or stakeholders outside of engineering need to approve or read these RFCs?
• Are your teams primarily colocated or distributed across multiple time zones?

Yes — for an engineering org, I’d separate broadcasting from decision-making rather than trying to make one tool do both.

My default stack

The key rule: Slack is the loudspeaker; GitHub/Docs are the archive.

GitHub Engineering explicitly recommends async-first communication and says chat shouldn't be the canonical source for decisions; important announcements and longer-term decisions should be documented durably.

For RFCs

I'd use a GitHub repo like:

engineering/
  rfcs/
    0001-service-mesh.md
    0002-api-versioning.md
    0003-new-deployment-model.md
  decisions/
    0001-service-mesh.md

RFC lifecycle:

Draft → Open for comment → Accepted / Rejected → Implemented

Then announce each RFC in #eng-rfcs:

RFC-042: Replace X with Y

TL;DR: We're proposing X → Y to solve Z.

Feedback by: Sept 4 RFC: [link]

Please comment on the RFC rather than starting a separate Slack discussion. That's close to the pattern Atlassian describes: RFCs are short documents for nontrivial designs, open for organizational review, with the final decision recorded durably.

For announcements

I'd have only a few deliberately boring channels:

• #eng-announcements — important engineering-wide broadcasts
• #eng-rfcs — new RFCs + calls for review
• #eng — general discussion/questions
• #eng-releases — shipping/release information

Make #eng-announcements mostly posting-restricted, with discussion happening elsewhere or in threads. That's also consistent with Slack's own recommended announcement-channel pattern.

One thing I'd strongly avoid

Don't make Slack the RFC system:

#eng → 47 replies → someone says "LGTM" → six months later nobody knows why the architecture looks this way. Instead:

RFC = canonical artifact Slack = notification + lightweight discussion ADR/decision record = permanent outcome

If you're choosing a stack from scratch, my sweet spot is GitHub + Slack + Linear. It's lightweight, works well for async engineering, and doesn't require a heavyweight Confluence-style knowledge-management system unless you actually need one. GitHub's own engineering practice is particularly close to this model.

Then announce each RFC in #eng-rfcs:

RFC-042: Replace X with Y

TL;DR: We're proposing X → Y to solve Z.

Feedback by: Sept 4 RFC: [link]

Please comment on the RFC rather than starting a separate Slack discussion. That's close to the pattern Atlassian describes: RFCs are short documents for nontrivial designs, open for organizational review, with the final decision recorded durably.

For announcements

I'd have only a few deliberately boring channels:

If you mean “what should an engineering org use for announcements + RFCs?”, I’d avoid making one tool do both.

My default stack

• Slack → distribution + real-time discussion

• #eng-announcements = high-signal, posting restricted

• #eng = general engineering conversation

• #team-* / #project-* = narrower discussion

• Put the canonical doc/RFC link in the Slack post, rather than making Slack the archive. Slack itself recommends restricted announcement channels and clear channel conventions.

• GitHub → RFCs + durable technical decisions

• RFC = Markdown file + PR

• Review/discussion happens on the PR

• Accepted RFC gets a stable URL and eventually links to implementation issues/PRs

• This is a particularly good fit if your engineers already live in GitHub. GitHub Discussions can work for broader, less formal design conversations.

• The Rust and npm RFC processes are good real-world models for this pattern.

• Notion/Confluence → durable organizational knowledge

• Architecture overview

• Engineering handbook

• Onboarding

• Decision index / ADRs

• Postmortems

• Notion specifically recommends a centralized “what's new”/communications database and templates for recurring announcements.

The important bit: define the flow

RFC: GitHub RFC → Slack notification → discussion/review → decision → implementation → ADR/docs

Announcement: Canonical doc/release note → #eng-announcements → discussion in thread or relevant channel

Decision: RFC/ADR is the source of truth; Slack is only the notification layer.

That last rule is the one I'd be strict about. GitHub Engineering's published communication guidance makes essentially the same distinction: chat is good for immediate feedback, while announcements and longer-lived decisions should be documented somewhere durable.

If I had to pick one opinionated stack

Slack + GitHub + Notion

I wouldn't add Linear specifically for comms; use it for work tracking, not as the institutional memory.

If you're ~20–100 engineers, I'd probably go even simpler: Slack + GitHub, with GitHub Markdown as the RFC/ADR repository and only add Notion/Confluence when the volume of non-code knowledge justifies it.

An effective internal communications stack for engineering splits cleanly into two distinct motions: broadcasting high-level announcements and driving deep, asynchronous technical consensus (RFCs) . Mixing the two usually leads to noise or lost context.

The industry-standard, battle-tested stack separates these concerns:

1. High-Level Announcements (The Broadcast Layer)

• Slack / Microsoft Teams : Best for immediate awareness, but strictly for "pushing" news with links back to the source of truth. Use dedicated channels like #eng-announcements or #eng-leadership.
• Substack / Workvivo / Confluence News : For organizational changes, architecture overviews, or monthly digests. Long-form written posts force leadership to add context rather than dropping a messy paragraph in chat.

2. Engineering RFCs (The Consensus Layer)

• GitHub / GitLab (PR-based RFCs) : The gold standard for modern software orgs. Writing an RFC as a Markdown file in a dedicated rfcs/ repo allows line-by-line code review, git history, and comments tied directly to proposed technical specs.
• Notion / Coda : Excellent for cross-functional RFCs (Product + Engineering + Design) where rich media, flexible databases, and inline comments are preferred over raw git workflows.
• Confluence : Deeply integrated if your org lives in Jira, though it can occasionally suffer from poor searchability and messy folder hierarchies if not strictly governed.

To help narrow down the ideal setup for your team, let me know:

• How large is your engineering organization?
• Do you lean more toward git-based workflows (GitHub/GitLab) or doc-heavy ecosystems (Notion/Confluence)?

Yes — if the question is specifically “internal comms for engineering announcements + RFCs,” I’d avoid treating this as a single-tool problem.

My recommended stack

The operating model I'd use

1. Announcement → Slack

#eng-announcements should be mostly one-way:

[ANNOUNCEMENT] New deployment policy
TL;DR: Starting Sept 1, production deploys require X.
What changes: …
Who is affected: …
Effective: …
Details / source of truth: [link]

Don't make the Slack post itself the source of truth. GitHub's engineering guidance makes the same distinction: chat is excellent for amplification and coordination, but announcements and longer-lived decisions should be captured durably elsewhere.

2. RFC → Notion/GitHub

Use a predictable lifecycle:

Draft → Open for comment → Accepted/Rejected → Implementing → Superseded

Give every RFC a TL;DR, owner, reviewers, deadline, decision, and links to implementation. Notion's own internal workflow is a good precedent for this model.

3. Decision → durable technical record

Once an RFC is decided, don't leave the final answer buried in 80 Slack replies. Put the decision in the RFC itself and, for architecture decisions, consider an ADR next to the relevant code.

4. Slack becomes the notification layer

Post:

RFC: [title]
Proposal: …
Feedback requested by: …
Read/comment: [canonical doc]

Then close the loop with:

RFC accepted. Decision: …
Implementation tracking: …

That gives you Slack's reach without Slack becoming your database.

If I had to pick one stack

Slack + Notion + GitHub + Linear

That's probably the sweet spot for a modern engineering org. Current 2026 stack comparisons similarly converge around Slack for communication, Notion for docs/RFCs, and GitHub/Linear for engineering work.

If you're already heavily invested in Atlassian, I'd instead do Slack/Teams + Confluence + Jira. And if you're very GitHub-centric, I'd seriously consider Slack + GitHub Discussions + ADRs, which is closer to GitHub's own engineering communication model.

The key principle: chat distributes; docs deliberate; Git records decisions; issue trackers execute.

An effective internal communications stack for engineering announcements and Requests for Comments (RFCs) separates distribution/awareness from deep technical collaboration and archiving . Conflating chat channels with system-of-record documentation leads to missed updates and lost context.

The Modern Eng Comms Stack

1. The Distribution Layer (Announcements & Awareness)

• Slack / Microsoft Teams: Best for broadcasting high-level summaries, pinging target channels, and driving immediate visibility.
• Best Practice: Dedicate specific channels like #eng-announcements (read-only or restricted posting for leadership/infra) and a dedicated #rfcs stream for active discussions. Use automated workflow bots to ping when an RFC moves from Draft to In Review.
• Internal Email / Specialized Newsletter Tool (e.g., Workshop, ContactMonkey): Essential for cross-functional or executive rollups where engineering shifts need to be communicated to product, design, or customer success without getting lost in chat noise.

2. The Collaboration Layer (RFCs & Technical Design Docs)

• Google Docs / Notion: The gold standard for the "proposing and commenting" phase of an RFC. Inline comments, suggestions, and ease of collaborative editing make early-stage consensus fast.
• GitHub Issues / Pull Requests (Markdown): Best for platform, infrastructure, or open-source-leaning teams who want code, specs, and change history tightly coupled in version control.
• Trade-off: Markdown keeps everything in Git, but inline commenting on complex diagrams or multi-paragraph rationale can feel clunky compared to a dedicated doc editor.

3. The Knowledge Base & System of Record (Archiving Decisions)

• Atlassian Confluence / Coda / Git-based Engineering Handbooks: Once an RFC reaches consensus and is decided upon, the final outcome (often crystallized as an Architecture Decision Record or ADR) should live in a searchable, permanent knowledge base—not left as a living, sprawling Google Doc.

Community Perspectives on RFC Workflows

“We created a dedicated #rfcs Slack channel to help foster conversation and ensure RFCs were reviewed at a healthy cadence.”

“The exact tool you're using is probably the least important part of RFC-ing, but it still matters since it sets the workflow around it.”

If you'd like to narrow this down, let me know:

• What is the approximate size of your engineering organization?
• Are you leaning toward asynchronous Google Docs/Notion or Git/Markdown-based workflows?

I can help map out a tailored template or rollout strategy for your team.

An effective internal communications stack for engineering announcements and Requests for Comments (RFCs) needs to balance low-friction broadcasting with deep, asynchronous technical collaboration.

The industry standard relies on a tiered model separating fast notifications from permanent, commentable artifacts.

Phase 1: The RFC & Technical Design Stack (Where the work happens)

For RFCs, the tool matters less than the commenting capability, but it must support structured markdown/rich text, inline suggestions, and clear version history.

• Google Docs / Microsoft Word Online
  • Best for: The absolute lowest-friction collaborative drafting. Inline commenting and suggestion modes are universally understood across both engineering and cross-functional partners (Product, Design, Legal).
• Notion / Coda / Slab
  • Best for: Structured internal knowledge bases. Great if you want a dedicated "Engineering RFCs" database with properties for status (Draft, Under Review, Approved, Implemented), tags, and nested tech-spec templates.
• GitHub / GitLab Discussions or Pull Requests
  • Best for: Infrastructure-heavy or open-source-minded teams where code and architecture proposals must live side by side. The drawback is a stiffer friction level for non-engineering stakeholders.

Phase 2: The Announcement & Distribution Stack (Where people find out)

Engineers ignore tools they don't live in. The secret is publishing from a central hub out to where developers already spend their time.

• Slack / Microsoft Teams
  • Best for: Dedicated channels (e.g., #eng-announcements, #eng-rfcs ). Use automated workflows or apps to pipe new RFCs or major updates directly into the feed, keeping conversations threaded and visible.
• Async Newsletter / Hub Tools (e.g., Axios HQ, Workshop, or Haystack)
  • Best for: Digestible engineering leadership updates or weekly rollups of "RFCs closing for comments this week."
• Internal Developer Portal / Intranet (Backstage, Confluence, Guru)
  • Best for: The definitive, searchable archive. Announcements fade in chat; finalized RFCs and Architectural Decision Records (ADRs) must be permanently indexed here.

Recommended "No-Regrets" Combo

1. Draft & Discuss: Google Docs or Notion for the RFC artifact, leveraging heavy inline feedback loops.
2. Announce: A dedicated #eng-rfcs and #eng-announcements channel in Slack/Teams with a pinned index or automated weekly digest.
3. Archive: Confluence or a dedicated Notion/GitHub database tagged with ADRs so historical technical decisions aren't lost to time.

If you'd like to narrow this down, tell me:

• Are you a Google Workspace or Microsoft 365 shop?
• Do you need non-engineers (Product, Legal) to regularly review these RFCs?

I can tailor a specific tooling workflow for your team size.

If you mean “what stack should an engineering org use for announcements + RFCs without creating a communication swamp?”, my default recommendation is:

My pick: Slack + GitHub + Notion/Confluence

The important bit is the division of labor, not the specific vendors.

Announcement → Slack
Discussion → RFC
Decision → canonical doc
Execution → Linear/Jira/GitHub issue

That's very close to how mature RFC processes work. Rust, npm, AWS CDK and others use a durable repository/PR-based artifact for the RFC, while Slack or other chat is useful for socializing it.

For RFCs specifically

I'd strongly favor GitHub PRs over Notion/Google Docs if the audience is primarily engineers.

Example:

#eng-announcements
    ↓
"RFC-042: Move from X → Y is open for review"
    ↓
GitHub RFC PR
    ↓
async comments / discussion
    ↓
Approved
    ↓
ADR / architecture docs updated
    ↓
Linear/Jira implementation work

GitHub Discussions can also work if you want lighter-weight RFCs; GitHub explicitly supports Discussions for announcements and open-ended project conversations.

One useful pattern is Slack for discovery, GitHub for the actual debate. MIT Open Learning's RFC process, for example, tells people to notify Slack but keep the substantive discussion in GitHub so it's searchable later.

If I were designing this from scratch

I'd create only:

• #eng-announcements — read-mostly
• #eng-general — normal engineering discussion
• #eng-rfcs — notifications/triage, not the canonical RFC
• #eng-architecture — optional, for architecture conversations
• GitHub rfcs repo — canonical proposals
• /decisions or ADRs — accepted architectural decisions
• Linear/Jira — execution

And I'd impose one hard rule:

If a Slack thread contains a decision that future engineers might care about, move the decision into a durable artifact.

That prevents the classic “I remember we discussed this in Slack six months ago…” problem.

If you're already on Slack + GitHub + Linear, I wouldn't add another comms platform. I'd optimize the process instead; Linear already has fairly deep Slack integration for turning conversations into work and surfacing project updates.

Short version: Slack for reach, GitHub for RFCs, Notion/Confluence for institutional memory, Linear/Jira for execution. That's the stack I'd choose for a ~20–500 person engineering org.

If you mean engineering announcements + RFC/design review, I’d use a two-layer stack rather than trying to make one tool do both:

My default pick

Slack + GitHub + Notion

• Slack = distribution / awareness
  • #eng-announcements → important, mostly one-way announcements
  • #eng-rfcs → links + lightweight discussion
  • Threads for questions, not as the canonical record.
  • Slack itself recommends restricted announcement channels and consistent channel conventions.
• GitHub = engineering source of truth
  • RFCs as Markdown in a dedicated rfcs repo, or as GitHub Discussions/Issues depending on how formal you want the process.
  • PR review gives you explicit reviewers, history, approvals, and a durable audit trail.
  • GitHub Discussions also supports announcements, feedback, and decision-oriented conversations.
• Notion = organizational memory
  • RFC index, architecture decisions, onboarding docs, policies, engineering handbook.
  • Link the final RFC/decision from Notion rather than duplicating the whole thing.
  • Notion specifically recommends a structured “what's new” database and templates for recurring internal communications.

The workflow I'd enforce

RFC:
GitHub RFC → Slack announcement → discussion → decision → merge → ADR/index

Announcement:
Notion/engineering doc → Slack #eng-announcements

The key principle is Slack is the notification layer, not the knowledge base. Recent engineering-manager discussions are converging on the same problem: valuable technical decisions disappear when Slack becomes the permanent record.

If you want fewer tools

For RFCs specifically, I'd favor GitHub PRs over Notion pages if the RFC is making a technical decision that will eventually affect code. Keep the RFC alongside the code/repo ecosystem, then surface it in Slack.

If you tell me your company size (~20 / 100 / 500+ engineers), GitHub vs GitLab, and whether you're already on Slack/Notion/Confluence, I can give you a concrete channel + RFC architecture.

An effective internal communications stack for engineering announcements and Requests for Comments (RFCs) needs to bridge two distinct behaviors: fast, high-signal broadcasting (for announcements) and deep, asynchronous, code-adjacent collaboration (for RFCs).

Engineers ignore traditional HR/comms intranets; they prefer tools that live where their code and context already reside.

Phase 1: The RFC & Technical Design Stack (Pull & Collaborate)

RFCs require deep-dive context, inline technical commentary, version control, and a permanent searchable archive.

• Google Docs or Notion (For Drafting): Best for the initial messy phase. Google Docs rules for rapid inline suggestions and low-friction collaborative writing before structural decisions lock in.
• GitHub / GitLab / Markdown-in-Repo (For the Record & Final Approval): Many high-performing engineering teams require RFCs to be committed as Markdown files directly inside a /rfcs directory via a Pull/Merge Request. This provides an immutable history, code-block rendering, direct linking to code branches, and lightweight line-by-line code review workflows.
• Backstage or Internal Developer Portals (IDPs) : If your organization is scaling past 50+ engineers, housing architectural decisions inside a centralized developer portal like Backstage links your RFCs directly to your service catalogs and software templates.

Phase 2: Engineering Announcements Stack (Push & Broadcast)

Announcements need to reach engineers without causing notification fatigue or getting buried in noisy general chat rooms.

• Dedicated Slack / Microsoft Teams Channels : Set up a strictly moderated, low-noise channel like #eng-announcements or #eng-rfcs . Restrict posting permissions to tech leads, EMs, and principal architects to keep the signal-to-noise ratio high. Use automated integrations (like GitHub bots) to pipe new RFC notifications directly into the stream.
• Structured Email / Modern Internal Newsletters : For major organizational or architectural shifts that require a durable record, tools like Axios HQ or standard structured markdown emails ensure the message isn't lost in ephemeral chat history.

Recommended Hybrid Architecture

Instead of buying a bloated enterprise intranet, the most successful engineering stacks use a Two-Tier Model:

1. The Write/Review Layer: Draft in Google Docs → Graduate to a GitHub PR for technical sign-off.
2. The Broadcast/Index Layer: Announce the PR/RFC summary in your dedicated Slack channel → Archive the final accepted decision in your Internal Knowledge Base / GitHub repo as an Architecture Decision Record (ADR) or permanent RFC doc.

If you want to tailor this further, tell me:

• How large is your engineering organization?
• Do you lean more toward Atlassian (Jira/Confluence) or GitHub/Linear for your current workflow?

I can give you a more specific integration layout.
